What is l when S = 725
This can be solved using Sum of n terms of an AP;
Where
To get T1; we substitute 4 for k in 2k - 3
To get Tn; we substitute l for k in 2k - 3
n = the number of terms;
Since k = 4 to l, then
Substitute these values in
Collect Like Terms
Open the bracket
Subtract 725 from both sides
or
or
But l must be positive;
Hence,
